[gdal-dev] Outline of world land masses

[Mike Slinn]

Martin,

You've got some interesting data.

Currently the program I'm working on is just for nautical navigation, so 
I'm more interested in the water side of the coastline ... however I 
would like to render the land as a filled region, and for that closed 
polylines are needed.

The details of the coastline are provided by S-57 charts (when loaded) 
however I'd like to have a low resolution image of the entire world for 
orientation purposes.

I'm going to try these images out later this week and will solicit 
feedback from my users:
